iPhone won’t update or respond
Hi, friend of mine have a problem with his iPhone. On the Lock Screen on his iPhone appears a message about the software update, but when we press the button update now the phone doesn’t respond. We tried to update it in iTunes, but it turned out that his iCloud is either not valid or it is not supported. We tried almost everything even the hard reset, but the phone is still not responding . If someone has the same problem, please tell us what we should do
